OpenSSL_add_all_algorithms, OpenSSL_add_all_ciphers, OpenSSL_add_all_digests, EVP_cleanup - add algorithms to internal table
#include <openssl/evp.h>The following functions have been deprecated since OpenSSL 1.1.0, and can be hidden entirely by defining OPENSSL_API_COMPAT with a suitable version value, see openssl_user_macros(7):
void OpenSSL_add_all_algorithms(void);
void OpenSSL_add_all_ciphers(void);
void OpenSSL_add_all_digests(void);
void EVP_cleanup(void);OpenSSL keeps an internal table of digest algorithms and ciphers. It uses this table to lookup ciphers via functions such as EVP_get_cipher_byname().
OpenSSL_add_all_digests() adds all digest algorithms to the table.
OpenSSL_add_all_algorithms() adds all algorithms to the table (digests and ciphers).
OpenSSL_add_all_ciphers() adds all encryption algorithms to the table including password based encryption algorithms.
In versions prior to 1.1.0 EVP_cleanup() removed all ciphers and digests from the table. It no longer has any effect in OpenSSL 1.1.0.
None of the functions return a value.
evp(7), EVP_DigestInit(3), EVP_EncryptInit(3)
The OpenSSL_add_all_algorithms(), OpenSSL_add_all_ciphers(), OpenSSL_add_all_digests(), and EVP_cleanup(), functions were deprecated in OpenSSL 1.1.0 by OPENSSL_init_crypto() and should not be used.
